Digital/Cyber/IT and
Non-Digital Services

Castellan Information Security is an end-to-end information security service provider. We work with clients to identify and address any gaps impacting their corporate, financial, personal, proprietary, and sensitive information.

Our differentiator is that we take a holistic/integrated approach to information security that focuses on digital/cyber/IT as well as information in non-digital forms.

Our services are designed to gather information from key resources within the client's business and identify gaps that present risks to company information. Assessors can examine four key areas within the client's organization followed by a report outlining key findings and recommendations.

Why Castellan?

Castellan's competitive advantage

We provide solutions, products and professional services that will enable and empower you to protect your information in all forms (physical and digital) against internal and external threats. There are very few of Castellan's competitors that provide any services that consider the physical security of information and because of this, there is a gap in the market for an end-to-end integrated information security services company like Castellan Information Security.

Castellan has a team of senior-level consultants from both physical and cybersecurity perspectives. Many of the consultants have over 25+ years of experience in delivering their services to clients in various sectors and of all sizes.

We also have strategic partnerships with key players and channel partners in the information security industry, ensuring you benefit from best-in-class solutions for our integrated approach.
